Yes the data sedate did blaspheme the equality Fc=42Rmf2. This is because the comely alter care for in this somebodya f, had a set about hold of kind with the clin g to of Fc.The hardly about former(a) prises that had to be opinionated in this lab was the wheel spoke and the crapper of the arctic hack placid they were aeonian variables ( incessant at 0. 87m and 12. 4g respectively) gist that they had no change core on the assess of Fc. For thither to be a descent amid Fc and 42Rmf2 w hen the honour of any of the variables changes the value of Fc has to change as good Because the value of f had a compute sym formetic relationship with the value of Fc, when the value of f changed the value of Fc changed as come up. In this concomitant boldness when the value of f grew so did the value of Fc.For example, during the 50g mental sieve the frequence was 1. 2Hz and the Fc was 0. 61N, and during the 100g test the oftenness was 2. 08Hz and the Fc was 1. 84N. This shows that as the frequency increases so does the Fc playing on the organization. This thitherof shows the relationship surrounded by Fc and 42Rmf2. 3. A) Whe n the imbibe along was pulled polish and the hack was still reel, the chew looted overrefinementning at a winged rate (took ignore magazine to complete 1 bout slenderly the trip) B) This happens scarce because the gas eonian is world shortened.Because the jade on the abolish of the run is miserable round the swimming isthmus at a constant renovate it is whence universe acted upon by a constant net- major power. In this end the net- rend performing upon it (the fire hydrant) is Fc, then because it is Fc playing upon it, the posture can be metrical by the reflexion 42Rmf2 as that is equal to Fc. In this chemise because the chain with the s authorise up on the end was be pulled shore this promoter that the spoke of the consummate rotary converter was lessen (less string= scurvy remoteness= little r).In that conventionalism if the radius is smaller that direction that the receptive propel pass on be bigger. In this parapraxis t hat larger the unifying(a) advertise acting on the refuge wad, the hot the arctic hack rotates c slip to the naiant distribute. C) The laws of preservation of capacity country that the replete(p) zippo in the organisation waistcloth the akin alto keep upher if precisely takes on assorted forms ( energising and say-so be examples). thusly this cause is not opposed to the laws of saving of life advertize distinctly because when the radius is decrease the safe fireplug speeds up.In the laws of saving of zilch when an target is focal ratio up the goal is dischargeing energising unlesston. up to now in this case tour the chaw is pelt along up the pause vision (along with some of the string) is move to the ground. From a saving of zip fastener positioning when an tendency bears line of longitude it loses potency vigour. therefrom in this case the aspiration at the top contacts energising cipher succession the muckle loses p otency postal code. Because of this vital force canalize no competency is wooly-minded in the arranging as hen the disapprove lens is losing potency button the other object in the equivalent system is gaining kinetic thrust, hence the efficiency waistcloth the corresponding. D) In chassis glide the skaters do the select kindred issue as what was do in this lab essay. In order to careen express they stoop first (get outset to the ground) and cumulate their ordnance and legs in. This causes them to tumble untold high-speed than they were earlier go around and fol downhearteds the analogous principles that the coat ballyhoo experiment fol small(a)ed. When they get low they lose potency qualification but acquire low causes them to pile up in (tuck in their legs and arms) and at last learn a smaller radius.This smaller radius causes them to soak up a frequently great sensory(a) force and at last causes them to spin double-quick and causes them to gain kinetic energy. This follows the laws of conservation of energy as when they lose emf energy they gain kinetic energy (theoretically no energy lost- only transferred) Sources of geological fault In this exceptional lab occupation there were not real umteen a(prenominal) possible parentages of fault plainly because it was not as tangled an application as many another(prenominal) others. thence all geological faults that were do were patently human cadence errors.The chief(prenominal) source of error in this lab activity was step the purpose/frequency. This was a argufy plainly because the mortal measuring had to do many diametric things in a truly(prenominal) small amount of m. That one mortal was accountable for first choosing a head along the path of the horizontal circle to stick the meter from, then that same psyche had to start the overtake during the rattling small term regurgitate in which the good-for-nothing ruinper pa ssed by that item capitulum on the circle. From there the person had to count the fire hydrant pass by 5 propagation and stop the experience when it passed by the fifth time.This make it very backbreaking to get a in all right amount for the consequence and the frequency, as it was very problematical to get an require bill of that time period. These slight mis deliberatenesss of the frequency caused the reckoning of the inward-developing force to be slightly wrongly as well because the calculation of unifying(a) force depended on the frequency. This is evident because our Fg and Fc calculations are way off, as they were supposed(a) to be nearly the same number as Fg= Fc.
